Frequently asked questions

What is the BH612321 Top Link Bolt used for?

The BH612321 is a 3/4 UNF x 4 inch bolt securing the front top link (upper radius arm) at both the chassis fulcrum bracket and the axle ball joint mounting. It maintains castor geometry and axle location at the upper suspension attachment on the Defender (1987-2016), Discovery 1 and Range Rover Classic.

How many of these bolts are typically needed for a top link replacement?

The front top link uses this bolt at both the fulcrum and ball joint end, so a single top link replacement typically needs two bolts. The Defender has one top link per side, so both sides typically need four in total.

Are there VIN restrictions for the Discovery 1 and Range Rover Classic?

Yes. For Discovery 1, the range is VIN FA393361 to WA799999. Range Rover Classic fitment covers two ranges: up to VIN HA610293, and from VIN JA610294. Defender fitment covers the full 1987-2016 production run.
